Jon's Altered Family

Jon went downstairs into the kitchen. He saw his dad, Alan, who was making something on the stove. Except for a pair of high heel shoes, his dad was completely nude, giving Jon a clear view of his naked ass. *Damn,* thought Jon. *Dad's ass is* cute*. But that's odd. He almost never cooks. Mom always does that.* Alan turned and said, "There you are dear. Sit down and get ready. We're almost ready to eat." Jon was stunned. His dad had a vagina, just like Jon did. And was that a bulge in his stomach? Could his dad be *pregnant*? Noticing Jon's stare, Alan caressed his stomach and said, "I'm really starting to show, aren't I? It seems like only yesterday I found out I was pregnant. My prenancies seem to be going by faster and faster. Now sit down, dear. You're father's home and I want to get started." Jon sat down. So his 'dad' was now his 'mom.' But who was his new dad?
